Not just a higher standard: certified

Significantly better homes don’t need to cost significantly more money to build or buy. The ENERGY STAR® for New Homes Standard helps builders construct homes that are significantly higher performing, using common building practices.


Using building science for a better home

Building an energy efficient home isn’t a matter of choosing vastly different materials. Building science looks at the elements that impact a home as a system: the building envelope, air quality, HVAC systems, building materials and even passive strategies that can be managed to optimize a building’s performance.

Through carefully managing how these elements work together, ENERGY STAR certified homes exceed current OBC requirements by 20 per cent on average, offering homeowners higher efficiency, greater durability and long-term operational savings.

Good building science equals better homes

Your application of building science to your structures will impact the quality of your home. The objective is a home that meets a higher standard:

  • Healthy
  • Safe
  • Durable
  • Efficient
  • Affordable
  • Sustainable

A better home can be less costly than you’d expect

Some parts of building a high-performance home may create an incremental cost of under $1,000—but there are opportunities for savings as well. These can offset one another, for a lower incremental cost than you might expect.
